. ATTORNEY Patented Oct. 25, 1932 UNITED STATES PATENT OFFICE DANIEL J. MAYER, OF BELLEVILLE, NEW JERSEY, ASSIGNOR TO METAL TEXTILE COR- IPORATION, OF WEST ORANGE, NEW JERSEY, A CORPORATION OF DELAWARE METALLIC ABRADANT Application filed September 16, 1931. Serial No. 563,114.

This invention relates to an improved construction of metallic abradant, and, more particularly, to a novel form and construction of metallic scouring device for scraping, cleaning and polishing the surfaces of kitchen and other utensils and other surfaces desired to be so treated.

Thisinvention has for its principal object to provide a hand implement comprising a spirally convolute strand of metallic wire looped back and forth upon itself and then more or less tightly twisted about its longitudinal axis to form a body in which the edges of the metallic convolutions are variously directed at many different angles, such twisted body being then turned lengthwise upon itself and secured, so as to provide a more or less "symmetrical and relatively compact mass which may be comfortably grasped by the user, and which is more or less resilient so as to be readily conformable by pressure to the surface towhich itmay be applied in use.

- The invention has for a further object to provide a metallic abradant of the kind above characterized, in which the convolutions of the metallic strand are so disposed at a great diversity of various angles that a multiplicity of scraping edges are formed, whereby sdme of said edges will be respectively, projected iri the many various directions of movement which may be imparted to the device when rubbing a surface to be scoured or scraped thereby, and consequently a high degree of abrading efficiency is attained in the use of the device; and, furthermore, owing to the character and form of the metallic strand, tendency of the device to dis integrate by splintering, shredding or sloughing off of metallic particles is avoided.

Other objects of thisinvention. not at thisv time more particularly enumerated, will be .understood from the following detailed description of the same.

Illustrative embodiments of this invention. together witha disclosure of one method of producing the same, is shown in the accompanving drawing, in which Fig. 1' is a face view of one form of the complete metallic abradant device according to this invention; Fig. 2 shows a hank of the spirally convolute strand of metallic wire looped back and forth upon itself preparatory to twisting the same to form the body of the device; Fig. 8 shows the hank after being twisted about its longitudinal axis preparatory to turning it upon itself into the desired symmetrical mass providing the finished device; and Fig. 4 shows a modified form of the finished device. 7

Similar characters of reference are em ployed in the above described views, to indi cate corresponding parts.

Referring to the drawing, the novel scouring device is made of metallic material, comprising a Wire which is turned or twisted upon itself to provide a roughly spirally convolved strand 5, or otherwise deformed to provide a multiplicity of scraping projections or points. flat ribbon-like form or of angular crosssectional shape, although wire of any crosssectional shape, round or angular may be employed. The flat ribbon-like wire, however, when spirally convolved, provides a multiplicity of chisel-like scraping edges or projections calculated to provide a maximum of abrading effect. While it is possible to use the metallic strand 5 alone, preferably, however,.a flexible carrier core of straight wire or textile cord 6 is employed upon and around which is convolved or gimped the metallic strand 5. Preferably the metallic material employed is of relatively non-corrosive character; for example, copper affords the best material both by reason of its relalength of the spirally convolved metallic strand is looped back and forth uponv itself Preferably the wire 1s of to form a hank 7 of desired length (see Fig. I

2). This hank 7 istwisted axially (as shown in Fig. 3), thus disposing the metallic strand in spiral turns, whereby the individual convolutions thereof are successivel shifted to various angles thus rojecting t e scraping ed es or projections ormed thereby in many di erent directions. The hank may be more or less tightl twisted. If tightly twisted, the resultant body will be less compressible or resilient and of a comparatively firm or hard density, whereas if less tightly twisted, a more resilient and fluflier character is imparted to the finished article. 1

'Upon completion of the wisted hank, the

same may be turned lengthwise upon itself to cause its opposite end portions, as a and b in Fig. 1 to meet, such meeting ends being thereupon secured together, as by a fastening staple 8, or by any other means or in any other manner, thus producing the finished device comprising a more or less symmetrical body A of annular form as shown in Fig. 1. The twisted hank may be otherwisemanipulated to produce the desired more or less compact body desired in the finished article. As shown in Fig. 4, for example, the twisted hank may be rolled lengthwise upon itself, with its inner end a and its outer end 6' secured or fastened by staples 9, or otherwise suitably secured, thus forming a finished device of general pad-like form B.

The endwise turning of the spirally twisted hank into the pad-like finished article further tends to distribute the convolutions of the metallic strand 5, which form the abrading or scraping edges, in a multiplicity of angular directions, especially along and about the outer surface of the finished device, all to the end that a maximum of abrading efliciency is attainablein every direction in which the device maybe rubbed over a surface to be cleaned.

Having thus described my invention, I claim 1. A scouring device, comprising a strand of metallic abrasive materlal looped back and forth upon itself and with the resultant mass twisted axially into a spirally formed body, said body being turned endwise upon itself with its free ends secured against displacement to provide a finished pad-like form.

2. A scouring device, comprising a strand of metallic abrasive material consisting in a flexible carrier core and a gimping of flat ribbon-like wire spirally convolved about said core, said strand being looped back and forth upon itself and with the resultant mass twlsted axially into a spirally formed body to disperse the convolutions of the gimping in a multiplicity of angles of projection, and means to retain the body against untwisting.

In .testimony that I claim the invention set forth above I have hereunto set my hand this 8th day of September, 1931.
